When it comes to monitor, the most visually striking feature we tend to notice is the brightness.

But what exactly does brightness mean in terms of monitors?

This easy-to-understand guide will explore everything you need to know about monitor brightness.

Quick Answer:

Monitor brightness determines the luminance of a display, affecting visibility and eye comfort; it’s adjustable to suit varying lighting conditions and personal preferences.

Monitor Brightness - Everything You Need To Know

Understanding Monitor Brightness

Simply put, monitor brightness refers to the amount of light the display emits.

It’s measured in candelas per square meter (cd/m2), also known as ‘nits.’

The higher the number of nits, the brighter the monitor.

What are Nits?

‘Nits’ is a measure of luminance or the intensity of visible light.

Technically, one “Nit” equals one candela per square meter (cd/m2).

This metric essentially tells us how much light the screen emits for every square meter of its size.

Why is Monitor Brightness Important?

Brightness affects how vivid and lively the images on the screen appear and how comfortable your viewing experience is.

If a monitor is too bright, it may strain your eyes, mainly when you use it for prolonged periods.

On the other hand, if it’s too dim, you might find it hard to see the details on your screen, particularly in a well-lit room.

Monitor Brightness - Everything You Need To Know

Types of Monitor Brightness

There are two types of brightness you should know about: ‘peak brightness’ and ‘sustained brightness.’

Peak Brightness

This term refers to a monitor’s maximum brightness level, but only briefly.

It’s beneficial in scenes with high dynamic range content, where the monitor needs to highlight specific parts of the image briefly.

Sustained Brightness

Unlike peak brightness, sustained brightness refers to the level of brightness a monitor can maintain over a long period.

This is typically lower than the peak brightness but reflects more accurately what you will experience during typical use.

Adjusting Monitor Brightness

Most monitors have controls that let you adjust the brightness to your preference.

These controls are usually in the monitor’s on-screen display (OSD) menu.

It’s crucial to adjust the brightness according to the lighting conditions in your room and your comfort.

Brightness and Monitor Types

Different types of monitors offer different levels of brightness. Here’s a quick rundown:

  • LED Monitor: These monitors are known for their excellent brightness levels, often reaching 300-350 nits.
  • LCD Monitor: These usually offer lower brightness levels than LED monitors, typically around 200-250 nits.
  • OLED Monitor: These screens can reach very high peak brightness levels, often over 500 nits, making them great for HDR content.

Frequently Asked Questions

Ques 1: What’s a good brightness level for my monitor?

Ans: Most people find brightness between 200 and 300 nits comfortable for everyday use.

However, this can vary depending on your room’s lighting and personal preference.

Ques 2. Can high monitor brightness damage my eyes?

Ans: Prolonged exposure to excessively bright screens can cause eye strain.

It’s best to adjust your monitor brightness comfortably and take regular breaks to rest your eyes.

Ques 3. Is monitor brightness the same as the backlight?

Ans: While both are related, they aren’t the same.

The backlight is the light source of the monitor, while the brightness is the amount of light the monitor emits.

Ques 4. Does higher brightness consume more power?

Ans: Yes, generally, higher brightness levels will consume more power.

So, adjusting your monitor to a lower brightness can help save energy.


Understanding monitor brightness is crucial for optimizing your viewing experience and ensuring comfort during long use.

Adjusting your monitor brightness to match your environment and personal preference allows you to enjoy a more comfortable and visually pleasing experience.
